RP2350-USB-A – A Raspberry Pi RP2350 board with an extra USB Type-A port using a PIO implementation

Waveshare RP2350-USB-A is a small Raspberry Pi RP2350  board with a USB-C port for power and programming and a USB-A port to use the board as a USB device or host through a programmable IO (PIO) implementation. The board also features an RGB LED and two GPIO headers, which could make it useful for controlling GPIO/I2C/UART/SPI-connected devices when connected to a USB keypad or similar input. Alternatively, it could emulate a keyboard, mouse, or other USB device when connected to a host. RP2350-USB-A specifications: SoC – Raspberry Pi RP2350A MCU CPU Dual-core Arm Cortex-M33 @150MHz with Arm Trustzone Dual-core 32-bit Hazard3 RISC-V @ 150MHz Up to two cores can be used at the same time Memory – 520KB SRAM Storage – 2MB SPI flash for firmware USB USB Type-A port connected to GPIO12, GPIO13, 5V, and GND USB 1.1 Type-C port for power and programming Expansion – 2x 9-pin 2.54mm […]

Credit card-sized quad relay board runs Tasmota firmware on ESP32 module (Crowdfunding)

The “ESP32 IoT Relay Board” is a credit card-sized ESP32 board with four small 250VAC/30VDC 7A relays that runs Tasmota open-source firmware and supports Alexa & Google Assistant for voice control. There are so many ESP32-based relay boards on the market that I don’t usually feel the need to cover new ones, but Igor Mileshin’s ESP32 IoT Relay Board is smaller than most so I thought it might be interesting to some. The smallest quad-channel relay board I’ve seen so far is the one by Seeed Studio using an STM32 MCU and solid-state relays that measures just 60 x 40mm, but the relays only support up to 2A. ESP32 IoT Relay Board specifications: Wireless module – ESP32-WROOM-32D SoC – Espressif ESP32-D0WD dual-core Tensilica LX6 processor @ 240 MHz Storage – 32Mbit SPI flash Connectivity – Wi-Fi 802.11 b/g/n up to 150 Mbps, Bluetooth 4.2/5.x LE Relays 4x “industrial-grade” relays supporting […]

UP Squared 7100 fanless SBC Review – Part 1: Unboxing and first boot to Ubuntu Pro 24.04

AAEON sent me a sample of the UP Squared 7100 fanless industrial SBC for review. The board is powered by an Intel N97 or N100 Alder Lake-N SoC (Amston Lake processors will be offered soon), and is equipped with up to 16GB LPDDR5 RAM and 128GB eMMC flash, plus two M.2 sockets for wireless and storage expansion. You’ll find the full specifications in our earlier article. I’ll start the review with an unboxing to check out the hardware, before booting it to Ubuntu Pro 24.04 LTS to check out some basic system information. In a few weeks, I’ll report my experience after in-depth testing in Ubuntu in the second part of the review which will include features testing from gigabit Ethernet to GPIO, some benchmarks, and power consumption measurements. UP Squared 7100 unboxing I received the UP Squared 7100 board in a retail package that reads “Are you UP for […]

The Deauther Watch V4S IR is a Wi-Fi hacker watch that can run up to 21 scripts via IR remote for wireless and HID attacks

We previously wrote about the Deauther Watch X used for wireless pentesting. The company has now released the Deauther Watch V4S IR an Wi-Fi hacker watch with a built-in infrared (IR) remote control for executing several scripts stored on a microSD card. It supports deauther attacks, Bad USB (HID) attacks, WiFi packet monitoring, and real-time clock adjustments. The new version features a 1,000mAh battery that can be charged via USB and it comes with includes a Type-C power cable, acrylic cover, and software manual. You can modify the Ducky Script inside the text files but must keep the filenames unchanged for proper operation. These features make this tool useful for cybersecurity professionals and enthusiasts for network security testing, penetration testing, and more. Deauther Watch V4S IR specifications: MCU – ESP8266 WiFi SoC @ up to 160 MHz with 160KB SRAM, 4MB SPI flash Storage – MicroSD card (preloaded with 21 […]

V-Link leverages GMSL2 to extend Raspberry Pi camera with up to 15-meter cable (Crowdfunding)

Videtronic’s V-Link is a compact solution designed to extend the range of Raspberry Pi MIPI DSI cameras using GMSL2 (Gigabit Multimedia Serial Link v2)  technology with up to 15-meter cables. We covered this type of solution in several NVIDIA Jetson Nano development kits and embedded computers, but never for the Raspberry Pi SBC. The V-Link relies on a MAX96717-based MIPI CSI-to-GSML2 board that connects to the MIPI CSI connector on the Raspberry Pi and a MAX96714-based GSML2-to-MIPI CSI board connected to the Raspberry Pi Camera Module. The solution provides an alternative to THine THSER101 Raspberry Pi camera extension kit that works with LAN cables up to 20 meters long. V-Link specifications Transmitter board Analog Devices MAX96717 CSI-2 to GMSL2 Serializer MIPI CSI input connector GSLM2 output connector Receiver board Analog Devices MAX96714 Single GMSL2/GMSL1 to CSI-2 Deserializer GSLM2 input connector MIPI CSI output connector to Raspberry Pi Camera Module Compatibility […]

Toradex launches its first SMARC modules with NXP SoCs for improved compatibility and supply chain

Toradex has introduced its first SMARC-compliant system-on-modules (SoMs) with the SMARC iMX8M Plus and SMARC iMX95 SoMs based on NXP i.MX 8M Plus and NXP i.MX 95 SoC respectively. The company has made proprietary system-on-modules for years with the Colibri, Apalis, Aquila, and Verdin families. Those typically are cost-optimized and use most or all I/Os from the selected SoC, but customers are tied to one supplier: Toradex. To offer more flexibility, the company decided to introduce its first standardized system-on-modules by selecting the SMARC 2.2 standard for compatibility with existing SMARC-compliant carrier boards and adding the Swiss company as an alternative supplier. Highlights of the SMARC iMX8M Plus module: SoC – NXP i.MX 8M Plus CPU Quad-core ARM Cortex-A53 application processor @ 1.6 GHz Arm Cortex-M7 real-time core @ 800 MHz GPU – Vivante GC380 2D GPU and GC7000UL 3D GPU VPU – 1080p60 video decoder & encoder AI accelerator […]
